Blade holder for safety razors whereby the stropping is facilitated



Patented Apr. 5, 1 932 UNITED STATES PATENT OFFICE JAMES WILLIAM AVONAND JOHN DOMINIC MASSEY, OF DRUMMOYNE, NEW SOUTH WALES, AUSTRALIA.

BLADE HOLDER FOR SAFETY RAZORS WHEREBY THE STROPPING IS FAGILI'IA'IEDApplication filed September 24, 1930, Serial No. 484,034, and inAustralia, August 14, 1930.

The invention relates to safety razors of the Gillette type and has forits object the provision of a blade holder and associated parts wherebythe razor may be used for shaving in the usual way, and with very little adjustment will provide for the sharpen- 111g of the blade upon anordinary strop of leather or other material.

According to our invention the blade is carried between twosemi-cylindrical parts comprising a blade carrier which is fixed, butcan be rotated when desired, in a frame slidable upon a handle.

A safety comb connected to the top of the handle is slidable in theframe and a clamp ing bridge has a projecting screw which. passingthrough the carrier into the top of the handle, clamps together thecomb, the carrier and the bridge.

When it is desired to strop the blade the bridge is removed and thestropping band passed between the carrier and the comb.

We will describe our invention in detail by aid of the accompanyingdrawings wheredrawn to a lar er scale.

Fig. 8 a plan thereof.

The razor blade 1 is fixed between the semi-cylindrical parts 2 and 3comprising a blade carrier, part 2 of which (as clearly 1-: shown inFigs. 7 and 8) is fashioned to provide two pairs of projecting springclips 1 and 5 positioned and adapted to fit into the holes employed inrazor blades of this type.

Part 3 has projecting snibs 6 and 7 which n fit into the opposing springclips 4 and 5 respectively, and secure the two parts of the carriertogether.

The parts 2 and 3 are hinged at one end by a pivot pin 8 passed througheyes 9 and 10 projecting one from each part, the eyes being formed sothat together they form a pintle of approximately rectangular crosssection.

Each part has at its end opposite to the hinge a projecting snib 11 and12 respectively, which when the carrier is closed down upon the bladecome into correspondence to form a pintle of rectangular cross section.

A handle 13 passes through and is rotatable in a frame 14 and is alsorotatably connected to a comb 15 slidable in the frame and having at itsends the projecting ears 16 and 17 respectively each of which has aguide hole through which a member of the frame passes.

The pintles at the ends of the blade carrier fit snugly into the upperends of slots in the ends of the frame members the carrier being therebynormally retained in position with the blade at right angles to the axisof the handle.

A bridge 18 has a projecting clamping screw 19 which passes through thecarrier and through the razor blade therein and screws into the upperend of the handle.

Fig. 1 shows the parts clamped together as they appear when the razor isin use for shaving.

When it is desired to strop the blade the bridge 18 is removed byturning the handle and thereby releasing screw 19. i

The comb is then slid upon the frame b the handle into the positionillustrated in Fig.

5 and the strop 20 (shown in dotted lines Fig. 6) is passed throughtheframe between the comb and the carrier. One end of the strop isconnected to a hook or the like in the usual way.

By drawing the razor to and fro over the strop with the handle at therequired angle thereto and altering the angle of the handle at each endof the stroke, one edge upon each side of the bladelnay be sharpened.

To enable the edges of the other side of the blade to be sharpened, thecarrier is slid down in the frame until the pintles at the ends of thecarrier pass into enlargements 21 of the slots in the frame memberswhich permit the carrier to be turned over. It is then returned to itsnormal position with the pintles fitting into the smaller parts of theslots in the frame.

When it is desired to remove the carrier from the frame to insert a newblade the frame members are sprung apart sufliciently to enable thepintles to be withdrawn from the slots.

It will be understood that we do not confine our invention to thedetails of construction shown in the drawings; for instance instead ofthe clamping screw projecting from the bridge and screwing into thehandle the screw may be upon the handle and engagea nut upon the bridge.7

F or the purpose of illustration we have adopted; the form of someparts, for instance the blade and bridge, which are common to existingrazors and which are conveniently adapted to our invention,'but theshape of such parts is generally a matter of design which may be variedto suit the principle of our invention.

We claim 1. In a razor of the type indicated a frame, a comb slidabletherein, guiding means for the comb,a handle slidable through the frameand rotatably connected to the comb, a blade carrier, pintles-one ateachend thereof carried in slots in the frame, a bridge adapted to rest uponthe blade carrier and a clamping screw projecting from the bridgethrough the blade carrier and screwing'into the end of the handle.

2. In a razor of the type indicated a frame, a. comb slidable therein,an ear upon each end of the comb, each car provided with a guide holethrough which a member of: the frame passes a blade carrier, a bridgeadapted .to

rest thereupon, and a handle rotatable in'the frame and rotatablyconnected to the bridge.

8. In a razor of the type indicated a razor blade, a carrier thereforcomprised of two parts between which the blade is received, hingingmeans connecting the parts at one end, spring clips projecting from onepart adapted to pass through holes in the blade,

snibs projecting'from the other part adapted to fit into the springclips, projections from the endsof both parts forming pintles ofrectangular cross section, and a frame having slots in which the pintlesare received.

l. In a razor of the type indicated a frame,

a comb slidable and guided therein, a handle slidable through the frameand rotatably connected to the'comb', a razor blade and a carrierthere-for having a rectangular pintle at each end, the frame havingslots in part of which the pintles are freeto rotate, and 1n other part.

are held from-rotation, a bridge, and a clamp ing screw thereon passingthrough the carrier into a screw threaded hole in the end of" thehandle.

In testimony whereof we have signed ournames to this'spe'cification;

(JAMES WILLIAM? AVON. JOHN DOMINIC MASSEY.
